R.-HADLEY AND WILLIAM A. VAWTER,

TEMPORARY HOLDER.

SPECIFICATION forming part of Letters Patent No. 475,259, dated May 17,-1892.

Application filed July 24,1891. Serial No- 400,563.' (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK M. TURCK,

of Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Temporary Holders; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

. This invention relates to devices for temporarily holding one or aplurality of sheets of paper between the covers of a book or holder,such as are commonly in use by shippin g-clerks, express-messengers, andthe like; and the invention consists more particularly in the meansemployed, whereby the sheets of paper are reniovably held in position.

The invention will be more fully understood by reference to theaccompanying drawings and description thereof, and will be moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective View of the device embodyingmy invention. Fig. 2 is an enlarged longitudinal sectional view thereof,taken upon line 2 2 of Fig. 1, the book or holder being closed andgrasping the sheet of paper. Fig. 3 is an enlarged longitudinalsectional View taken on the line 3 3 of Fig. 1 with the lids of the bookthrown back and opened for the ready removal of one sheet of paper andthe insertion of another, as will be hereinafter explained. Fig. 4 is anenlarged perspective View of the springclamping device, constituting theback and a part of the hinge. Fig. 5 is a sectional view taken on theline 5 5 of Fig. 2, Fig. 6 is a sectional view taken on the line 6 6 ofFig. 2. Fig. 7 is a detail View of the canvas, showing the slitstherein.

In the drawings, let A represent the top board or lid, A the bottomboard or lid, and B the spring-hinge back to which each of said boards AA are inovably secured or hinged in the manner hereinafter stated. Thespringback B, as more clearly shown in Fig. 4, consists of a strip ofmetal, U-shaped in crosssection, the two side margins 12 of which arebended toward each other at b and then inwardly, so as to normallyapproach and bear against each other, as clearly shown in Figs. 2 and 4.At suitable intervals along the margin or bend b the said margin is cutaway or recessed, as clearly shown in Fig. 4 at 19 C C are rods, one ofwhich is inserted in each of the grooves or angles at the margins 19,formed by bending the said margins 17 inwardly at b.

D is apiece of canvas or other suitable flexible material glued orotherwise secured to the outside surfaces of the top and bottom boards Aand A, and which extends, also, around the outside of spring-back B, andprovided between said spring-back B and the rear edges of the boards A Awith a slack portion or cover d. D is asimilar piece of canvas or othersuitable flexible material extending partially over and secured to theinner surfaces of-the boards A A, and also extending over the. outersurfaces of the spring-back B, between it and the piece D. At thosepoints of the canvas covering D that register with the ends of thecut-away portions b of the back B said canvas lining D is apertured orslit, as shown at d. The apertures or slits d are formed in a slackportion 01 of the piece D, intermediate between the back B and boards Aand A, and those portions of the slack portion d between each pair ofapertures or slits d form loops d which extend into the cutaway portions5 of the margins 19 of the spring-back B, with which they correspond innumber and location. When the rods C C are inserted in their places,they are passed through the loops d of the piece D, being insertedthrough the several apertures or slits d, which are at the ends of saidloops, and thus serve to connect the piece D to the spring-back B atboth of its margins.

E is a block of wood adapted to fit over a portion of the bottom rearedge of the back B, as shown in Fig. 3and as indicated in dotted linesin Fig. 1. This block E constitutes no part of my invention, but is acommon and well-known device employed for assisting the user of theholder in overcoming the force of the spring-back when desiring to openthe boards.

The operation of my device is as follows:

The parts being as shown in Fig. 2 with a desirable to open the same forremoving said sheet or inserting another, the block E is applied in themanner indicated in the draw.-

ings, whereupon boards A and A are turned back into the positionindicated in Fig. 3, and, resting on said block E as a fulcrum, serve asa lever to force apart the meeting edges of the spring-back B by forceapplied to the said boards at their free ends in a well-known manner.The sheet F may then be removed or another sheet inserted, whereupon theboards A A are released and the parts resume their normal position,firmly clamping what sheets may be in the holder.

It will be seen that the structure forms a simple and efficient meansfor connecting the spring-back B with the remainder of the holder, andthat the rods 0 0 maybe readily Withdrawn and inserted to disconnect orconnect the said back. It will be observed that the inwardly-bentmargins of the spring-back B form two continuous clamping-pieces 19reverse in position with respect to the body of the spring-back, thuspresenting a flaring opening to guide the sheet which is beinginsertedinto position between them when the back isforced open, said clamping-pieces having an elasticity of their own independent of andadditional to that of the spring-back, whereby they hold theinsertedsheet or sheets with a firm yet yielding pressure, thus effectuallyclamping the same without injury.

What I claim is- 1. In a temporary holder, the combination, with aspring-back having grooved margins cut away at intervals, of front andback boards connected by a piece of canvas or the like passing aroundthe back and apertured or slit at intervals corresponding with those ofthe cut-away portions of the margins of the back to form loops, and rodslocated in said grooved margins of the back and passing through theloops of the connecting-piece, substantially as described.

2. In a temporary holder, the combination, with a spring-back havinggrooved margins cut away at intervals, of front and back boardsconnected'by an outer piece of canvas or the like passing around thesaid back, an inner piece of canvas or the like also passing back boardsand apertured or slit at intervals corresponding with those of thecut-away portions of the margins of the back to form loops, and rodslocated insaid grooved margins of the back and passing through the saidloops, substantially as described.

3. In a temporary holder, the combination, with the front and backboards, of a spring metallic back U-shaped in cross-section,hav-

ing its longitudinal edges bent at intervals to extend reversely inwardtoward and to each other to form clamping-pieces, a piece of canvas orthe like passing around the said front and back boards and thespring-back, and means, substantially as set forth, for holding saidcanvas in place, whereby said front and back boards and the saidspring-back are joined together, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
